ABSTRACT:
This invention relates to a method of bridge erection i.e., an arrangement for erecting a bridge girder. More particularly, it is concerned with an erection method, in which a bridge girder is smoothly extruded, together with a movable member, on a temporary support member which is disposed on an upper shoe until the girder reaches a position near the installation position, whereupon a coupling member for connecting the upper shoe with a sole plate which is pre-fixed to the girder, is attached to the sole plate, then in this condition the girder is again moved forward up to the installation position while pushing the end portion of the temporary support member on the upper shoe by the coupling member so as to displace the temporary support member and the movable member by the coupling member, whereby the bridge girder and the support structure are fixed in engagement with each other without the need to lift the bridge girder.
